Hi, I have one page session-bom.php, in which computer parts are availlable for shopping. e.g. mouse , keyboard ect. with the checkbox. and textboxes to enter quantity and label of prices. When user hits 'submit' button, only selected parts goes to the bill.php page and showing their price multiplied by quantity. , and grand total.
Everything works with session except grand total. plz. guide me that why my grand total gets wrong.
Here are attachments.
